I hope that if it turns out to be some kind of premonition, it at least gets hinted at that Picards connection to the Borg made it possible.Somebody asked back a few pages how I had determined that Dream-Data's Five Queen of Hearts was significant...
I'd suggest going back and listening to Narek & "Lt. Rizzo's" conversation in the hallway.
She very much demands that he find out from SOji where the Other's are hiding. and just how many there are.
Again, we know there are at least Five from Dream-Data and his poker hand.
The Writer's were practically telling us outright with that.
